. HORSESHOE-BENDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 406,713, dated July 9,1889. Application filed February 15,1889. Serial No. 800,037. (llomodel.)

T0 on whom it may concern; I

Be it known that we, WILLIAM EYN ON and WILLIAM SEAMAN, both citizens ofthe United States, and residents of Wilmington, New Castle county,Delaware, have invented certain Improvements in Horseshoe-BendingMachines, of which the following is a specification.

The object of our invention is to construct a machine of a simplecharacter for rapidly bending into horseshoe form straight blanks, thelatter I being preferably creased beforehand, so that after beingsubjected to the action of thebending-machine they form finish ed shoes,with the exception of the nail-holes.

In the accompanying drawings, Figure 1 is a plan view of ahorseshoe-bending machine constructed in accordance with our invention,the cams on the die-carrier being omitted to avoid confusion. Fig. 2 isa longitudinal section on the line1-2, Fig. 1, showing the greaterportion of the machine in elevation. Fig. 3 is an end view of themachine; and Figs. at, 5,

and 6 are diagrams illustrating the operation housings of the machine,having suitable bearings for a shaft B, to which a rotating movement isimparted from a counter-shaft a, through the medium of a spur-pinion band spur-wheel b, as shown in Figs. 1 and 3, the shaft to being drivenin any suitable manner. Secured to the shaft 13 is a disk D, which has aseries of projections, each carrying a dieblock D, the bases of thesedie-blocks being beveled, and the projections of the disks beingprovided with dovetailed recesses for the reception of said beveledbases, so that the die-blocks can be readily secured to or removed fromthe disk, as required, each dieblock having on its outer face aformer-die d, of the proper shape for the shoe to be bent.

Projecting inward from the opposite end frames or housings of themachine are curved benches or tables F, which are slightly eccentrio inrespect to the axis of the die-carrying disk, for a purpose describedhereinafter. On

the upper portion of each of these tables F is fixed a die f, bevelednear its outer end, counter-dies f working in conjunction with saidfixed die f, being carried by the upper ends oflongitudinally-swinginglevers G, which are suitably hung to bearings onthe end frames of the machine, and are acted upon by cams g on theopposite faces of the die-carryin g disk D, as the disk D revolves inthe direction of the 5 5 arrow, Fig. 2. 011 the ends of the die-carryingdisks are other cams h, acting upon anti-fric tion rollers t', carriedby the lower ends of transversely-swinging levers ll, which are hung tobearings in the end frames of the ma- 6o chine and carry at their upperends rolls m.

The operation of the machine is as follows: The dies f being withdrawnto their farthest extent from the dies f, a blank 00 is laid upon theopposite tables F F, in front of the dies f and in advance of theapproaching former-die (Z. The dies f are then advanced by the action ofthe cams g upolrthe levers G, so that the ends of the blank are nippedand squeezed between the beveled ends of the dies f f,

and the proper'taper is thereby imparted to said ends of the blank, asshown in Fig. 4. The advancing former-die (Z now strikes that portion ofthe blank which bridges the space between the opposite tablesF F, andthe dies f having receded from the fixed dies f, the blank is carriedforward, the ends of the blank passing clear of the dies f and beingbent around the former-die d into a position parallel with the plane ofmovement of said die,

as shown in Fig. 5. As the former-die dis passing the rolls on at theupper ends of the levers H, the anti-friction rollers carried by thelower ends of said levers are acted upon by the cams h of thedie-carrying disk, and said rolls m are caused to advance, so as topress the rear ends of the blank inward against the contracted rearportion of the former-die (l, as shown in Fig. 0. The blank thus bentaround the former-die overhangs the inner 9o number of dies used, themachine being 'pe'r- .roo

fectly automatic in its operation-that is to say, no manipulation of theblank being re- By mounting the quired other than the placing of itinproper position on the machine in the first instance. Having thusdescribed our invention, We

claim and desire to secure by Letters Patent 1. The combination of therotating die-holding disk, supports for the opposite ends of the blank,beveled pressingdies for acting on said opposite ends and tapering thesame before the blank is bent aroundthe former-die as the latteradvances, levers carrying the movable pressing-dies, and cams upon thedisk for actuating said levers as the disk rotates, substantially asspecified.

' 2. The combination of the rotating dieholding disk, supports for theopposite ends of the blank to be bent, dies for pressing the ends of theblank, rolls for pressing said ends inward against the contracted rearportion of the former-die, levers carrying the movable dies and rolls,and cams at the ends of the die-car rying disk for actuating saidlevers, substantially as specified.

3. The combination of the rotating disk having dovetailed projections,With the dies having dovetailed bases secured Within the dovetailedrecesses of the projections, substantially as specified.

4. The combination of the rotatingdiecarryin g disk, and the diesrigidly mounted there-
